- robots.txt
- Sitemap
- Link response headers
Top fix: Add a sitemap.xml and reference it in robots.txt to allow indexing of pricing and documentation pages.
- Markdown content negotiation
Top fix: Enable text/markdown content negotiation so AI agents can consume API docs and pricing without parsing HTML.
- AI bot rules in robots.txt
- Content Signals
- Web Bot Auth
Top fix: Implement .well-known/http-message-signatures-directory to authenticate legitimate AI agents instead of blocking them entirely.
- MCP Server Card
- Agent Skills index
- API Catalog
- OAuth / OIDC Discovery
- OAuth Protected Resource
Top fix: Add an agentskills.json and .well-known/api-catalog to expose the email sending and inbox creation endpoints to autonomous agents.
- x402 Payment
- MPP
- UCP
- ACP
Top fix: Implement x402 or ACP to enable native agentic payments for the existing USDC credit system.
Biggest opportunities
- 1Unblock GPTBot and ClaudeBot in robots.txt or implement Web Bot Auth to allow AI discovery of the email API.high impact · small effort
- 2Create an agentskills.json file defining 'send_email', 'create_inbox', and 'check_balance' skills.high impact · medium effort
- 3Enable Markdown content negotiation for API documentation and pricing pages.medium impact · small effort
Critical issues
- Explicitly blocks major AI crawlers (GPTBot, ClaudeBot) despite being a product designed specifically for AI agents.
- Zero protocol discovery endpoints (MCP, AgentSkills, API Catalog) making the API invisible to autonomous systems.
- No standardized agentic commerce protocols despite relying on crypto payments.
What's working
- Significantly lower price point ($12/mo) compared to competitor AgentMail.to ($20/mo).
- Native Solana USDC integration allows for permissionless, global payments without traditional banking.
- Specialized features like persistent agent memory and wallet-based inbox recovery tailored for autonomous workflows.
